Does it bother anyone else that we plan to bury millions of tons of carbon? |
|
These notions of 'clean coal' that suggest we will capture CO2 and then bury it are as bothersome to me as the Yucca Mountain project is to the anti-nuke crowd. Here's the difference as I see it. With the nukes we know a billion or more dollars has been spent finding the best place on earth to do it (if its going to be done) and hundreds and hundreds of millions have been spent building the facility not to mention the decades of planning by some of the nation's best minds. With the carbon sequestration schemes it will be every power plant out there digging holes on their own. Hard to see where that could go wrong. Oh, another alternative they are planning is deep ocean deposit. It seems if you can find water deep and cold enough the carbon dioxide compresses into some crap that DOE swears won't hurt a thing.
All these carbon capture and sequestration schemes really scare me, its like sweeping shit under a rug and expecting no smell.

You can figure out the potential results for yourself. EIA: http://www.eia.doe.gov/oiaf/aeo/overview.html#ercarbon

3. Potential results could actually be beneficial for the environment |
|
Add pressure over millions of years, and we get diamonds
Add it to crops and you can make fertilizer
Carbon isn't a bad thing in itself - its when its airborne that we have a problem

4. maybe after a million years it'll turn into nice, clean coal |
|
or maybe DIAMONDS (drool)
Don't worry, we can put it right next to the plutonium pond.
don't check--FULL STEAM AHEAD!!!!

9. I would rather secure a hunk of spent nuclear fuel the size of a doublewide than |

try to hide 5 million trainloads of toxic fly ash and other combustion products.

12. I don't worry about it. |
|
Keep in mind that vast sections of the Earths surface is already covered by, or covering, limestone, which is essentially sequestered carbon. The only real question is the stability of the sequestration medium. Frozen deposits on the ocean floor have been stable for hundreds of millions of years. Depleted oil wells tap underground pockets that have been sealed since the Carboniferous. There are plenty of places to store the carbon that are secure, but will we use them, or just pump & pray?
